Abstract (en)

[origin: WO2005090373A1] The binuclear, oxygen-bridged, hetero-bimetallic complexes of general formula [(LM<1>R<1>)(Cp2M<2>R<2>)]ñ-O) are suitable as polymerization catalysts for olefin polymerization. (M<1>= Al, Ge, Zr or Ti; M<2>= Zr, Ti or Hf; Cp = cyclopentadienyl; R<1>, R<2> = methyl, ethyl, i-propyl, t-butyl, halogen, phenyl, alkylphenyl, SiMe3; L = bidental, doubly nitrogen-coordinated organochemical ligand, which together with metal M<1> form a 5- or six membered ring). These complexes have very good catalytic activity, good useful life and require less cocatalysts.
